This invention relates nto a window construction in whicha sash is mountednet only for verticalsliding movementin 21 trains but aisofor pivotal movementabout a horiz'ontal axis to various selective positions.

One objei't of this invention is-the provision ofan improved means for slidably mounting a sash of the character described for vertical movement-ins frame. v

Another object is the provision of a sin'ip'le means for releasably holding a sash ona plurality of angular positionsalmut a horizontal axis. 1 i

In the drawingsi Fig.1 is an elevationpartlyin section; of the improved window construction;

Fig. 2 is a sectional View looking'towards the left in Fig. 1;

Fig. 3 is a. plan view an-d Fig. 4 is an enlarged sectional view showing a sash in a sloping position.

The frame of the window is shown as consisting of a plurality of upright members 2 to which are secured upwardly extending strips 4, 6 and 8. The adjacent sides of which are'shaped to form channels 10 and 12 of T- shaped cross-section. It will be obvious, of course, that these channels might be formed otherwise than as shown on the drawings, for example, by being cut in blocks of wood or metal. The upper sash assembly slides in guideway 10 while the lower sash assembly slides on guideway 12. Since the sashes are of similar construction, and each is symmet rical about its vertical center, only one-half of one of the sashes need be described in de tail, for example the left hand portion of the lower sash which is viewed from the inside of the window in Fig. 1.

A block 14 of T shaped cross-section slides on guideway 12 and is secured by a cord 16, passing over a suitable pulley at the top of V the frame, to a counter-balancing weight 18 of the ordinary type.

located a sashholding assembly 22. It will be clear that only one of these need be pro videdfor each sash, although two are preferably used to prevent excessive strains on one. so Each assembly consists of a plate 24 pivoted on a stud 26 extending outwardly from block In the lower corners of each sash 20 there is RISER, or mannerisms,

14. Theplate 24 is rigidly secured to the sash and accordingly stud 26 acts as apivot for the sash. 1 A plate 28 isfixedlysecured'to the portion-of stud extending through plate 24, 4

sothat plate 28 remains stationary relatively to bl'ock'14. Plate-28 has a suritace extending about stud 26 which is notche'cL-as shown, to providestops 30 and 32', arranged for-engage ment by pawl 34 pivoted at36 to plate 24and provided with a stop engagingnose 38-. Pawl 34 is made'of enlargeddin'iensionsas shown,

so that it maintained normally by ilsown weight withits nose contactingwith plate 28. If a. more positive engagement is desirethit may be keptin position by a suitable spring;

A lever 40 is pivotally secured at its lower end, as sh0w=n,-to plate24 and is provided-with an internal opening forming two arm pieces 42 and 44 respectively arranged-to contact with pin 46 carried by plate 28. Its upper end is turned at 48 to form an arm engageable with the lower face of pawl 34.

To illustrate the operation of the mechanism described above reference may be made to .the upper sash in Fig. 2 in which the parts are shown in the positions they occupy when the sash is closed. In this position nose 38 is out of contact with the circumferential surface of plate 28. If the sash is now swung downward contact between arm 48 and pawl 34 is maintained by friction until nose 38 clears stop 32. As soon as stop 32 is cleared, the further movement of the sash causes arm face 42 to engage stationary pin 46, arresting further movement of arm 48 with the pawl and permitting the pawl to drop into contact with plate 28 and engage stop 30. Stop 30 is so positioned that when the parts, following the above described movement, are in the positions shown on the bottomsash in Fig. 2, the sash is in a horizontal position. However, it will be clear that the stop may be so positioned that the sash is sloping.

If the sash is now raised, nose 38 rides up the sloping face of the notch above stop 30 and drops above stop 32. If the sash is then allowed to move slightly downwardly it will be maintained in the position shown in Fig.

4. During such raising of the sash lever 40 is maintained out of contact with the pawl by pin 46, or, after pin 46 allows the lever i to swing against the pawl, the pawl itself sash is obtainable in the structure described,

it' will be obvious that a plurality of stops 32 may be provided which will. be adapted to engage the sash during its upwardmovement.

The assembly 22 may be suitably located in a recess in thewindow covered by .plates 24, 50, and 52, the lower end 54 of which last plate may be curved for clearance. The assembly is desirablylocated on the sash but obviously it may be located inblock -14, stud 26 being secured to the sash. 1

To hold the sash in vertical position, a latching means maybe" provided at its upper corner. This may consist of a recess in the sashcovered by a plate 56 slidablyhousing latch 58 carrying a knurled knob 60 engageable by the fingers and projecting through a slot in. plate 56; Latch 58 may be spring pressed if desired'into'engagement within one of guideways 10 0112 and is suitably notched at 62 for the passage of cord 16. v

WVhat is claimed is:

1. A window structure comprising a frame having upwardly extending guideways, blocks slida'ble in said guideways, a sash pivoted to said blocks, the sash and one block forming relatively "movable members arranged toTbe releasably held in a plurality of for so holding said members; including a pawl on one member and a plurality of stops on the other member selectively engageable with said pawl.

2. A. window structure comprising a frame having upwardly extending blocks slidable in said guidew'ays, a sash pivoted to said blocks, the sash and'one block forming relatively movable members arranged to be releasably heldina plurality of for so holding said members including a pawl on one member, a plurality of stops on the other member selectively engageable with and stop when the members are relatively moved in the opposite direction.
